Norton 66623340172 Deburring Disc 6in Extra Coarse Silicon Carbide

Product Description

The NORTON 66623340172 is a rigid silicon carbide deburring disc designed for aggressive material removal on metal, composites, and other hard surfaces. At 6 inches in diameter and 0.5 inches thick, this disc mounts via a 3/8-inch arbor hole and is rated to a maximum of 8000 RPM. The extra coarse grade and density-7 construction make it well suited for rapid deburring, edge conditioning, and surface prep work where a finer finish is not the priority. Fabricators, metalworkers, and maintenance technicians are the primary installers and users of this disc.

This deburring disc is used in fabrication shops, manufacturing facilities, and field maintenance applications where metal edges and surfaces need fast material removal. Its rigid construction keeps the disc from flexing under load, maintaining consistent contact with the workpiece. The silicon carbide abrasive is effective on non-ferrous metals, cast iron, stone, and certain composite materials. It is sold individually with a minimum order quantity of 25 units.

Key Features

• Extra coarse silicon carbide abrasive for rapid deburring and edge conditioning
• Rigid disc construction maintains consistent contact with the workpiece
• 3/8-inch arbor hole center for secure mandrel or arbor mounting
• 8000 RPM maximum rating supports use on standard angle grinders and disc sanders
• Density 7 construction balances aggressiveness with disc durability
• 0.5-inch thickness provides stability during heavy-duty surface prep

Compatibility

Designed as an OEM-style replacement or standard-fit deburring disc for grinders and disc sanders accepting a 6-inch diameter, 3/8-inch arbor-mount disc.

Installation Notes

Installation should be performed by a qualified fabricator or technician familiar with abrasive disc equipment. Always power down and disconnect the tool from its power source before mounting or removing the disc. Verify the tool spindle speed does not exceed the 8000 RPM maximum rating of the disc before operation. Inspect the disc for cracks or damage before each use and follow applicable ANSI B7.1 safety standards for the mounting and use of abrasive wheels.
